Specification of Letters Patent No. 27,787, dated April 10, 1860.

To all whom 'it may concern.'

Be it known that I, JOHN M. FARNAM, of Hartford, county of Hartford, and State of Connecticut, have invented a new and usew ful Improvement in Machines for Sharpening, Cleaning, and Polishing Knives and Forks; and I do hereby declare that the same is described and represented in the following specification and drawing.

To enable others skilled in the art, to make and use my machine I will proceed to describe its construction and operation referring to the drawings in which the same letters indicate like parts in each of the figures.

This machine is intended to be used as a knife sharpener and knife and fork cleaner and polisher, the polishing plates being so arranged as to admit freely at one endany ordinary sized fork and shaft to the handle while the other end will admit only the blade of the knife between the polishing plates, and the hoppers for holding the polishing powder are supplied with gates which operate both as feeders and shut offs of the powder at the will of the operator.

A more correct understanding of its nature construction and operation will be derived from an examination of the accompanying drawings.

Figure I is a side view of the machine showing nearly all of the operating parts in detail. Fig. II shows the hopper with the gate in position of feeding.

A represents the frame of the machine. B represents the lower polishing plate secured at one end by the pin a and at the other end resting upon a spiral spring b.

C represents the upper polishing plate secured in its place by the pin c near its center and to which is attached the knife sharpener G Gr and the powder holders or hoppers D, D.

D, D represents the hoppers or holders of the powder used for polishing.

E represents the feed gate by the operation of which t-he powder is fed through the upper plate upon the lower one or retained in the hopper at the will of the operator.

F represents the shafts by which the gates are operated.

G, Gr represent two steel plates adjusted and attached to the upper plate for the purpose of sharpening knives.

Z) Z2 represent two spiral springs arranged at either end of the frame as adj usters of the plates.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The arrangement of the polishing plates B, C, to be used in the manner and for the purpose described substantially as herein set forth.

2. The arrangement of attaching the knife sharpening plates Cr, Gr, to the plate C, to be used for the purpose described substantially as set forth.

3. I claim the gate E constructed and combined with the hoppers D, D as and for the purpose specified.

4. I claim the combination of the polishing plates B, C, the hoppers D, D', with the sharpening plates G, G, and spiral springs Z), b, constructed and arranged as and for the purpose specified.
